Optiflex 1100C TDR level transmitter

The Optiflex 1100C from Krohne is a 2-wire TDR level transmitter for measuring distance, level, volume and mass of liquids and solids.

Its simple, compact design allows users to quickly assemble the probe and attach it to a threaded connection. The device has been designed with no brittle parts and is always top-mounted or in a bypass cage.

It is suitable for applications that do not require a high level of accuracy and is an alternative to traditional level controls such as RF capacitance, conductive and DP transmitters.

As TDR is a time-of-flight measurement and measures distance, usual variations of the dielectric constant - such as those due to a change of process temperature - do not impact the accuracy of the level measurement.

Its performance is not influenced by sludge in the bottom of a tank, nor by dust, foam, vapour, agitated or boiling surfaces, changes in pressure and temperature or changes in dielectric constant and density.

The 1100C offers good repeatable signal for storage of general liquids and solids, buffer tanks, sludge and condensate collectors and more simple process applications.
